My invention relates to improvements in Agarbage and refuse incinerators of the type adapted especially for "use in apartment buildings, residences, hospitals, and the like;

and it has for one of its objects to provide a simple and inexpensive incinerator where` in garbage or refuse can be consumed con'- vemently, economlcally, and 1n a cleanly and sanitary manner, and which, by means of a smoke pipe or flue, is connected to a chimneyl of the building in which the incinerator is situated.

Another object of my invention is to provide a gas-burning down-draft incinerator, and particularly one in which the air mixes directly with the gas above the garbage or refuse being consumed. Y

A further object of m invention is to provide an incinerator in w ich the gas burner is located in a lane above the charging or feed opening, and wherein the major portion, at least, of the garbage or refuse to be consumed occupies the space between said opening andl the grate.

A further object of my 'invention is the provision of an ineinerator wherein the gas burner attacks the garba e or refuse from the top, and the flame o the burner burns from the top downwardl so that it attacks, at all times, the portion o the arbage or refuse having least moisture, and by reason of the draft beingv downwardly' through the nrarbage or refuse, gradually dries the garbage or refuse from the top downwardly,

with the result that ractically all of the garbage or refuse will e consumed and only a comparatively small quantity of ash or waste result from the operation of incinerating the garbage or refuse.

A still furtherobject of my invention is to provide an incinerator having a gas burner so disposed therein that the direction of the flame and draft is downwardly through the garbage or refuse and wherein the draft pipe or fiue has its'inlet opening in a. plane below the lowest portion of, the garbage or refuse receptacle orcontainer. f v y A still further object of my invention is to provide an incinerating chamber having imperforate walls and a gratedike or openy3 -3, Fig. 1.

work receptacle' or container having a perforated bottom and at least-a rear imperforate wall of the incinerating chamber to form an auxiliary Hue, and a draft pipe or flue having an inlet connected with the lower `end 'of said auxiliary flue.

lVith the above and other objects in view to appear hereinafter, my invention consists in the novel features of construction and in the arrangement and combination of parts to be hereinafter descbed and ymore particularly pointed out in the subjoined claims. In the drawing:

Fig. 1 is a central vertical section throu hY an incinerator constructed in accordance with my invention.

Fig. 2 is a horizontal section taken on line' 2-2, Fig'. 1. v

Fig. 3 is a horizontal section taken `on line The reference numeral 4 designates the casing of the -incinerator, which comprises a top wall 5, a bottom Wall 6, a front wall 7, opposite side walls 8, and a rear wall 9,tl1e latter being curved and merging intothe side walls 8, as at 10. The front, side, and rear walls constitute a surrounding 'wall and each comprises an outer wall portion 11 lined with asbestos 12 in sheathing or other suitable form for insulation pur oses, and an inner wall portion 13 spa/ced rom said out-l er wall portionto form an intervening air space orpassage 14, said air space or passage extending 4from the'bottlom wall 6 to thetop wall 5. l

WVithin. this incinerator casing a transverse wall or what may be termed a back plate, .15 Isarranged, which extends from side wall to side wall. and between which and the front wall 7, the inc-inerating'chamber 16 is arranged.

jfAt the bottom of the front wall 7 a door opening 17 is provided, which is closed by a door 18. Near the u per end of said front wall, a charging or fee l opening 19 is formed which is also closed by a door 2O.l y

Arranged within the incinerating cham- -ber 16v is a basket-like garbage or refuse receptacle'or container 21 formed of openworkl or grate-like walls. This receptacle 100 or container comprises a bottom wall or grate 22, a front wall 2 3, side Walls 24, and a rear wall 25, the front wall being inclined downwardly and rearwardly from its upper end, as clearly shown in Fig. 1, while the rear wall has its lower portion inclined downwardly and forwardly approximately from a point midway between the upper and lower ends of said receptacle or container to said glrate 22; thus gradually 'reducing the cross-sectional area of the receptacle downwardly. While this formation is desirable, owing to the fact that the front wall and the lower portion of the rear wall are thus spaced gradually increasing @distances from the ront wall 7 of the casing and the back plate 15, respectively, it is to be understood that this garbage or refuse receptacle or container may be otherwise constructed. Although the grate 22 is shown as non-shakable, or non-movable, it is of course to be understood that it is within the province of thosel skilled in the art to which this invention relates, when constructing the incinerator, to provide shaking, rocking or other movable bars;

for, if desired, an integral grate movable or rockable in any desired manner.

It is to be noted that the rear wall 25 of the garbage or refuse receptacle or containof said receptacle or container, as shown at" 26. The rear wall of the garbage or refuse receptacle or container is spaced from the 'rear wall or back plate 15 of the incinerating chamber, and this space serves as an auxiliary flue 27, which extendsfrom the upper end bf said reary wall downwardly into the ash pit 28 beneath the receptacle or container 21. ,f i

The receptacle or container 21 maybe supported in any practicable manner, but 1n the construction illustrated, the front wall 23 thereof has a forwardly extending flange 29, which-,rests upon a supporting rib 30 formed on the front inner wall 13 ofthe incinerator casing,'while brackets or supports 31 fastened to the rear. wall or back plate 15 of the incinerating chamber are secured to the rear wall of said receptacle or lcontainer and support the same from the rear.

The side walls 24 of the receptacle or container 21 are spaced from the side walls 8 of the incinerator casing so that the openwork walls of said receptacle or container are spaced at all points from the surrounding walls of the lincinerating chamber.

The rear wall or back plate 15 'of the incineratin chamber has a laterally elongated opening ormed therein near its lower end, and fitted into this opening is the corres ondingly elongated end of a smoke or dra box 32, the inlet opening of which is therefore of considerable area. This draft box is situated in the flue `chamber 33 between the rear wall or back plate 15 of the incinerating chamber and the curved rear wall 9 of the incinerator casing. This smoke or draft-box is provided at the top with an outlet opening 34, and connected to this opening is-a smoke or draft pipe 35 which extends upwardly through the flue chamber 33 and ,out through the top 5 of the incinerator casing. To the upper end of this smoke or draft pipe 35 is adapted to be secured a suitable pipe or flue leading to a chimne of the building in which the incinerator 1s situated, so that connection is had directly with the incinerating chamber 16 to establish a means of escape for the unconsumed gases or smoke.

36 designates a gas burner, which may be of any approved construction, and which is situated in the upper end of the incinerating chamber 16y a suitable distance abovethe garbage or refuse placed within the receptacle 0r container 21. This gas burner extends out through the front wall 7 of the incinerator casing and is adapted to have connection with any suitable source of gas supply and provided with suitable means of control, as will be understoodcto those skilled in the art.

The gas burner 36 is directed downwardly so that the flame issuing therefrom will be directed against thel top of the garbage or refuse contained in the garbage or refuse receptacle or container 21.

It is the general practice in garbage or refuse incinerators of this type to fill the garbage or refuse receptacle or container with the garbage or refuse and allow the same to dr if moisture laden, before incineration ta es place. Consequently, the upper portion of the garbage or refuse will dry out before the lower portion, and when 'burned from the bottom', or from the sides, the wet portlons first are attacked, causing excessive smoke and im erfect combustion, unless the "t garbage or re use accumulated is allowed to vremain in the receptacle or container for an impracticable length of time, in order to-assure complete drying of the same from top to bottom. In this improved incinerator,

lwhen the upper portionfof the garbage or refuse is freed of moisture, at least to a degree found desirable before commencing incineration thereof, the burner 36 is ignited. The flame directed against the top of the garbage or refuse will attack and gradually consume the same, and as the walls of the refuse. receptacle are all provided with openings and the inlet to the smoke or draft box 32 is in a plane beneath said receptacle, it will be clear vthat the direction of the draft andi the effective action ofthe flame will be in a downward course, thus drying out the lower portion of the garbage while consuming thc upper. Be-

period of time than heretofore ossible, or will at least be reduced to ashes. his results in a saving of gas, eliminates smoke and odors and assures clean surroundings.

By reason of having the rear wall 25 of the receptacle or container` 21 extended upward- 1y, the fiame from the burner will also be directed rearwardly through the upwardly extended portion of said rear wall and thence downwardly, with the result that the garbage within the receptacle or container will also be attacked from the rear, and as the draft in the auxiliary flue 27 in rear of said rear wall is downwardly, the smoke and gases will pass downwardly through said flue, also from the sides of the receptacle or container, and escape through the inlet of the smoke or draft box 32, from which it- Will pass upwardly through the smoke or draft pipe 35 and be drawn into the chimney.

It is highly essential that the proper quantity of air be provided to the incinerating chamber, especially to the flame of the gas burner, and for this purpose the bottom wall 6 of the incinerator casing is provided with numerous air openings 37, said openings being alined with the air space or passage 14 between the outer and inner Wall portions of the casing. The air entering these openings travels upwardly through said space or passage and enters air openings 38 formed in the inner wall portion of the casing at opposite sides of the incincrating chamber, preferably at their extreme upper ends. The air thus entering the incinerating casing commingles freely with the gas escaping from the burner 3G and furnishes the proper amount of oxygen necessary to provide a hot flame and to furnish the garbage or refuse where attacked by the ame, with the necessary quantity of air to assure proper combustion.
